There is a java.lang.ClassCastException: ejb.persistence.User.
My servlet code is:
private void showUser(HttpServletRequest request,
| HttpServletResponse response) {
| try {
| InitialContext ctx = new InitialContext();
| userSession = (userSession)
ctx.lookup("userSessionBean/local");
| } catch (Exception e) {
| e.printStackTrace();
| }
|
| Collection<User> auser = userSession.getUsers();
| if (auser != null)
| for (User user : auser) {
| System.out.println("User name : " +
user.getName());
| System.out.println("User id : " + user.getId());
| System.out.println("User mgs : " +
user.getMessage());
| }
| }
userSessionBean/local getUsers method code is:
| public Collection<User> getUsers() {
| // TODO Auto-generated method stub
| return em.createQuery("from User u").getResultList();
| }
My ejb.persistence.User class is:
| package ejb.persistence;
|
| import javax.persistence.*;
|
| @Entity
| @Table(name = "user")
| public class User {
| private String name;
|
| private int id;
|
| private String message;
|
| public User() { }
|
| public User(String name, String message) {
| this.name = name;
| this.message = message;
| }
|
| @Id
| @GeneratedValue
| public int getId() {
| return id;
| }
|
| public void setId(int id) {
| this.id = id;
| }
|
| public String getMessage() {
| return message;
| }
|
| public void setMessage(String message) {
| this.message = message;
| }
|
| public String getName() {
| return name;
| }
|
| public void setName(String name) {
| this.name = name;
| }
| }
Sorry for the long post, hope you're still with me. My questions is:
Why is there a ClassCastException occured? What's wrong?
